Lenovo E540 Standby Problem on Ubuntu 14.04

UPDATE: Lenovo fixed the Bios, after a bios update standby + USB 3.0 enabled work. I used the geteltorito.pl-method descriped in the thinkwiki: http://www.thinkwiki.org/wiki/BIOS_Upgrade


I was furious about a very annoying standby problem my new Lenovo Laptop had. When closing the lid or choosing standby by the menu I did not hear the disks and fans spin down. Instead it kept running. When I then opened the lid, the backlight or something else shined, but the display stayed all black. The only solution was to keep the powerbutton pressed for a hard shutdown. The only solution for now seems to be to:

deactivate USB 3.0 in the Bios

Not cool. But at least know you have the choice with which shitty situation you want to live. With slow usb, or without standby. For more information in detail, read here. It seems to be a Lenovo Bios Problem: https://bugzilla.kernel.org/show_bug.cgi?id=80351
